Nowadays, numerous chemical and physical methods are being used for modification of properties of textiles. In recent years, due to stringent ecological restrictions, textile industry has been forced to use green and eco-friendly technologies. Ultraviolet (UV) irradiation, as a clean, eco-friendly, simple, inexpensive, and promising technology has been extensively used for surface modification of fibers and production of functionalized textiles. UV irradiation enhances dye-ability, color strength, wet-ability and reduces pilling and felting and does not impair bulk properties such as strength and handle. In addition, using UV technology, optimal dyeing time and temperature can be decreased resulting in saving energy and lower process cost. The aim of this study is to review the latest literature published on the applications of UV irradiations for modification of properties and characteristics of natural protein (wool and silk) and cellulose (cotton) fibers. For this purpose, different types of UV sources, ranges of effective UV irradiation, and its application in different industries as well as modification of fibers are described. Then, the results of the latest investigations are reviewed according to natural fiber type of wool, silk and cotton.

Colour and colour selections are mostly important and fundamental factor in designing a therapeutic and a healthcare centre. Patients and visitors of a healthcare center are affected by environmental colour design, and thus, a lack of appropriate use of colours in a medical center, is a kind of injustice during the process of recovery. This kind of mistakes is so harmful for people visiting healthcare centers and it could not be forgiven. Colours, forms and space are considered as an effective factor to accelerate the recovery and treatment of patients. The precise design with the proper application of colours and lightings in a hospital environment, obligates a lot of important benefits for patient, staff, and visitors over the years. Considering the aspect of aesthetics, color can provide appealing and attractive conditions for patients, visitors and staff. Nowadays, the knowledge of color psychology is a professional necessity for hospital engineers in order to design a better environment. The current collecting has been defined to review methods and suggestions for appropriate colour selections in hospitals. In this paper the principles of color psychology has been reviewed and the solutions for colour design problems in hospital environments are introduced, and finally, the suitable colours in designing public healthcare centers would be suggested

Nowadays, due to the ecological and health concerns associated with the use of synthetic dyes, there is a great tendency for the use of natural dyes in the dyeing of textiles, especially natural fibers. Unlike protein fibers, cotton has a very low affinity toward the natural dyes and the dyed goods have low fastness properties besides low color strength. In this study, several investigations reported on the improvement of natural dyeing of cotton fibers have been reviewed and classified. Different methods including the use of metal mordants, enzymes, bio-mordants, cationic and anionic compounds, amine compounds, ultrasound, gamma rays, plasma technology, UV rays and microwave have been considered and the results of the reported literature have been reviewed.

In this review paper, Epoxy-based nanocomposite coatings are focused that are produced by hyperbranched polymer-modified nanofillers. At first, keywords like epoxy, nanocomposite, hyperbranched polymer are defined and then fabrication methods and modification of nanocomposite coatings, various categorizations, advantages and disadvantages are investigated. Consequently, the effect of modification and addition of different nanoparticles on the characteristics of the coating such as physical-mechanical properties, anticorrosion and dispersion level are reviewed. Considering the discussions it can be concluded that using hyperbranched polymers as modifier for nanoparticles in order to improve the dispersion and its stability and increasing the various properties of the nanocomposite coatings, is useful and promising.

Today, more than 75 percent of total polyurethane consumption in the world is in the form of foam, and a significant proportion of these foams are used in coatings in various industries. The production and consumption of these types of coatings have a growing trend due to reasonable price, making lightweight structures, excellent adhesion to substrates, quick and easy curing at ambient temperatures, high durability, ability to cut and form into various types and shapes, their ease of application, optimal mechanical properties such as high resilience, compressive strength and etc. Polyurethane foam coatings are used in building and transportation industries as thermal and acoustic insulation coatings, flooring, wall buffers in community halls, and so on. Two reactions of gelation and blowing carried out simultaneously in foam admixture. The final properties of foams depend entirely on the structure, stability and geometry of the foam cells which are function of the relative rate of these two reactions. So controlling of reaction rates in the direction of the optimal final product are essential. The controlling factors of these two reactions include of temperature, the presence of an amine or organic-metal catalyst and isocyanate index. The most important factor determining the properties of polyurethane foam is its cellular structure. In this review study, comprehensive information was collected about the role of materials, chemical reactions during foam formation, physical and chemical structure of cells and the factors affecting the final properties of cellular coatings
